Carrier aggregation for LTE-advanced: functionality and performance aspects [PDF]
IEEE Communications Magazine, 2011 Carrier aggregation (CA) is one of the key features for LTE-Advanced. By means of CA, users gain access to a total bandwidth of up to 100 MHz in order to meet the IMT-Advanced requirements. The system bandwidth may be contiguous, or composed of several non-contiguous bandwidth chunks, which are aggregated. This paper presents a summary of the supported
